xgcpLowerBoundForJitter
Module: XGCP-MIB
OID (symbolic): XGCP-MIB::xgcpLowerBoundForJitter
OID (numeric): 1.3.6.1.3.90.1.4.3
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object is the lower bound for Quality Alert for Jitter.
Jitter is an estimate of the statistical variance of the RTP data packet interval-rival time measured in milliseconds and expressed as an unsigned integer.
When jitter(milliseconds) is long enough to reach lower bound(e.g.30 ) and then higher bound(e.g. 150) the first time, a MGCP/SGCP Notify message is sent to the Media Gateway Controller.
Subsequent hits of the higher bound results in a MGCP/SGCP Notify message being sent to the Media Gateway Controller only after the lower bound is hit.
The default value of this object is 30.
What is xgcpLowerBoundForJitter?
The lower jitter threshold, in milliseconds (4-60, default 30), used for voice-quality alerting on RTP packet interarrival variance; a Notify message fires the first time jitter climbs from this lower bound up through the higher bound (xgcpHigherBoundForJitter), then again only after dipping back below this lower bound.
